Description
Summary:Technological progress creates new challenges, especially in the areas of energy savings, environmentally friendly materials and sustainable development. These challenges exist for electroinsulating materials, including electroinsulating fluids. Finding substitutes for the petroleum-based fluids used in electrotechnics is not a simple task. It involves the geopolitical location of the manufacturer and the user of the machine, fluid prices and fluid parameters. The electrical parameters, along with various other properties, of newly proposed fluids need to be evaluated over a long period of simulated operation in order to determine their suitability for use in power transformers. New international standards are being developed to address this issue. Many laboratories around the world are searching for an acceptable new insulating fluid. This paper presents the results of a study of newly proposed and prepared mixtures of insulating fluids with higher flash points and suitable electrical parameters.
